Effective immediately only the registered trainers of greyhounds engaged will be permitted to attend race meetings.
A concession has been made for trainers with more than four greyhounds engaged at a meeting to allow them one attendant.
The move comes just one day after GRNSW and GWIC released a stricter full race day procedure policy.
Trainers and race club staff will need to make themselves available to catch other greyhounds on race day.
GWIC have relaxed the rule where a catcher must catch just one greyhound. A single catcher will be able to catch more than one greyhound for the foreseeable future.
